Most fbdev drivers operate on I/O memory. And most of those use the
default implementations for file I/O and console drawing. Convert all
these low-hanging fruits to the fb_ops initializer macro and Kconfig
token for fbdev I/O helpers.

The fbdev I/O helpers are easily grep-able. In a later patch, they can
be left to empty values if the rsp. functionality, such as file I/O or
console, has been disabled.

There are no functional changes. The helpers set the defaults that
the drivers already use. The fb_io_*() functions that the initializer
macro sets are the defaults if struct fb_ops.fb_read or .fb_write are
NULL. After all drivers have been updated to set them explicitly, the
defaults can be dropped and the functions can be made optional.

v3:
	* use _IOMEM_ in commit message
v2:
	* updated to use _IOMEM_ tokens
